To all lwhom t may concern:

`Lubricators, of which the following is a p specification.

My invention relates to multi-ply leaf spring lubricators of the type shown in my pending application, Serial No. 828,137,filed March 30, 1914, although in a broader sense itis applicable to lubricators of other forms which are designed to lubrcate the contact surfaces ofmulti-ply leaf springs. It has for its principal object the provision of a lubricator adapted to deliver lubricant to the contacting surfaces of multi-ply leaf springs and held, longitudinally of the spring, in fixed relation to the spring seat orsupport. With this object in view I have devised means for the attachment of leaf spring lubricators which may be readily secured in place so that the lubricator may properly perform its functions and not work loose or become shifted by the continual inter-action between the spring leaves which goes on whenever the vehicle to which the spring is attached is in motion.

In the general construction of vehicles the spring is seated'upon and secured to the vehicle axle or to the vehicle frame or body. It is at,.0r,in fixed relation to such a spring seat or supporting and anchoring member that I 'secure the lubricator attachment Referring to the drawings, Figure 1 is a side elevation of a leaf spring mounted upon an 'axle and equipped with a pair of twosided lubricators secured or anchored in `rig. 3- is Section on 1in@ r11-nr of Fig. 2.V

mounted upon anaxle and equipped with a pair of two-,sided lubricators secured in position in a modifiedl manner.

Fig. 7 is an enlarged part section on line VII-VII, Fig. 6 and part sideelevation of the structureshown in Fig.` 4.

Fig. 8 is a plan view of a leaf spring mounted upon an axle and equipped with a pair of single sided lubricators, applied to the same edges of the spring leaves and secured in substantially the manner shown in Figs. 11 and 5.

Fig. 9 is a side elevation of the structure shown in Fig. 8.

Fig. 10 is an enlarged section on line X-X of Fig. 9.

Fig. 11 is a plan view of a leaf spring 'mounted upon an axle and equipped with a pair of single sided lubricators applied to opposite edges of the spring leaves and secured in the manner shown in Fig. l.

Fig. 12 is a sideelcvation of the structure shown in Fig. 11.

Fig. 13 is a side elevation of a quarterellipt'ic leaf spring secured to the frame or body of a vehicle and equipped with only one lubricator which may be either single or double sided.

Referring to Figs. 1, 2 and 3, reference numeral, 1, is a multi-ply leaf spring of the well known semi-elliptic form; 2 represents the axle of a vehicle to which spring, 1, is secured by means of the usual spring clips, 3, 3. The customary assembling bolt, 4:, is shown having its head, 5, serving as a dowel pin in a suitable recess in the axle for the purpose of-positioning the spring thereon. Assembled with the spring are the lubricators 6, 6, which are shown formed integrally with or fixed to the connecting and anchoring member, 7, which extends along the bottom of the spring and is held in place by the spring clips, 3, 3, and assembling bolt, 4, exactly as though it were a spring leaf.

The lubricators, 6, 6, are shown as being of the type `in which pads of fibrous, absorbent material, 8, 8, saturated with oil, are held underlimitod compression against the edges of the spring leaves in compartments formed by the walls, 9, 9, of the lubricator, the edges 9a of which are bent in toward the spring to retain the pads from endwise displacement. A metal cap, ,10, is shown extending across the top of the spring, and connected to the' side walls, 9, 9, by the riveted projections, 9b. The height of the side walls, 9, is such that the`lubricaters, 6, do not clamp the`leavesofthe spring and they are, therefore, as free to slide and vibrate upon each other as though the lubricators were not present. It will be seen that the lubricators thus `far described i are held by means secured at the point `where the spring is anchored to the vehicle `axle by the same means by which the spring is secured to the axle. It is to be noted also that the lubricators, thus secured,` cannot be displaced by the movement of the spring leaves upon eachv other.

In Figs. 4, 5, 6 and 7, is shown-,a pair'of lubricators, 13, 13, secured in a modified manner from that shown in Figs. 1, 2 and 3. In the form of attachment shown in Figs.

4,5, 6 and 7, connecting member, 14, extends I along the top of the spring, and is provided with afhole at the centerv through which an assembling bolt, 15, passes. AY nut, 16, secures the connecting member, 14, to the top of the spring, 17. This means of attachment may be advantageously used upon springs which are already assembledgupon the vehicle and provides a convenient means for mountingthe lubricators upon the springs without `removing the springs from the vevhicle. The sidewalls, 18, 18, ofthe lubri-y cator shown in Figs. 4, v5, 6 and7, are shown formedintegrally with the connecting member, 14, although it is to be understood that they may be separately formedand attached tothe connecting member. The bottom ends,

' 19, ofthev side walls extend, downwardfbeyond the spring as shown in Fig. 6, and a plate, 20, is secured to them forthe purpose of retainingfthe lubricating pads, 21, in position. The end walls, 18a, 18a, ofthe lubricator, arebent in toward the spring to retain the lubricating pads, 21, vin longitudinal po# sition and to complete the compartment in which thefpads are located. It will be seenthat` the lubricators shown in Figs. 4,5, 6,

and 7. areheld by means secured at a point which is fixed inrelation tothe spring seat and the supporting axle.

Inv,Figs. 8, 9 and'10, I have shown single sided lubricators in which the lubricating pads are applied' to only one edge ofthe leaf spring. In this-form the single sided lubricators,v23,` `23, are shown connected by al springmetal plate24, extending along one side of the leaf spring and shaped so as to clear the spring clips, 25. An angle piece, 261,. isfformed from orattached tothe connecting member, 24, and iss arranged to be secured. upon the spring assembling; bolt,

I 27by the nut, 28, in a manner silnilar to the method of securingtheconnecting member,..14, tothe bolt, .15, shown inv Figs. 4 and 5.. The lubricator, 23, will beseen to be a shallow, rectangular. vcompartment having an opens-idef presented to the. edges ofthe spring` leaves and containing the lubricating; pad, 29,.y f y f .Y .In-Figs. 11f and l2, I have showna form of. single sided` lubricator similarY to that i shown'in Figs.v 8, 9 and 10, with'tlie exception-that instead of beingapplied t'ogthe same-.edge ofthe spring, thelubricators,y 31,.

are applied to opposite edges of the spring, and instead of being attached to the spring in the manner shownin Figs. 8, 9 and 10, the method of attachment shown in Fig. 1 is followed, the connecting member, 32, being shown as extending along the bottom of the spring, 33, and being clamped with the springto the axle, 34, by t-he clips, 35, and held in position by the assembling bolt, 36.

In Fig. 13 I have shown ay form of lub ri. cator similar to that.y shown VVin Figs. 4, 5, 6

and7, but, in Fig. 13, I- employ only one.

lubricator, 37, as it is applied toy what is commonly known asa quarter-ellipticv spring. The connecting member, 38, is

clamped under the spring, support, 39, be-r tween it and the spring, 40,-as though the connecting member were one of the leaves of the spring. It willbe apparent thaty the` lubricator, 37, may haveonly la single-pad applied to yone edge.y ofthe spring leaves,-

simi-lar to the type shownin .Fig.\8,- or it.

may be double sided andy have two pads similar tothe type shown in Figp. Y

It will also beunderstood that any wellknown provision may be made for injectingv oil into the lubricantholding pads in the particular type of lubricator lherein shown,

and-.that .various changes and modifications of myinvention ymay be made withoutdeparting from its scope.,
